666720-54-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 666720-54-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,6,7,2 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 666720-54:
(8*6)+(7*6)+(6*6)+(5*7)+(4*2)+(3*0)+(2*5)+(1*4)=183
183 % 10 = 3
So 666720-54-3 is a valid CAS Registry Number.
